A metal is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. Metals are typically malleable or ductile. Wikipedia
metal, any of a class of substances characterized by high electrical and thermal conductivity as well as by malleability, ductility, and high reflectivity of light. Approximately three-quarters of all known chemical elements are metals.

Metal oxidation takes place when an ionic chemical reaction occurs on a metal’s surface while oxygen is present. Electrons move from the metal to the oxygen molecules during this process. Negative oxygen ions then generate and enter the metal, leading to the creation of an oxide surface.

Metal related definition
(Record 1 of 2) 8: various opaque, low-melting, elastic and therefore usually shiny substances, which are undoubtedly good conductors of electricity and heat, form cations by losing electrons, and emit basic oxides and especially hydroxides: a good chemical element in different from the new coarse alloy.
What is a metal answer
Metals are naturally occurring compounds in the earth’s crust, commonly found as minerals that are beneficial to each other and also associated with many other elements.
What is metal and its example
Alloys are clearly mixtures where at least one object of the mixture is one. Examples of metals are aluminum, water pipes, iron, tin, gold, silver, lead, titanium, uranium and zinc. Known alloys include steel. The studied metals are called metallurgy.
What is metal explain for kids
Metals are minerals found underground in rocks, lead or iron. They are separated from the rocks with the help of heat. Metals are very useful materials. Metals use many properties such as strength, durability, and rigidity. When heated, metals turn into everything from a small, important paper clip to a giant bow tie.

Why are metals good conductors of electricity
Why are electrical and thermal conductors valuable? Metals form gold bonds, which means that the electrons are delocalized.
Their delocalized electrons can carry energy, charging the metal.
Your delocalized electrons will transfer energy thermally.
The atoms that make up the material form a matrix in which external electrons can freely move through the metal.

What are some of the characteristics of metals
The metals have a typical metallic salty luster (as the name suggests).
Non-metals can give different lusters such as vitreous, pearly, dull, resinous, greasy, diamond-like, etc.
Metals conduct heat and electricity. Nonmetals are usually conductors or semiconductors.
Metals do not react with water, so they do not break down in water.
